All my projects use existing Makefiles. We have a series of setup scripts that setup all of or build anc ClearCase environment. I launch netbeans once I've run the setup. The problem is that we use a few environment variables to point to external library dependencies (root directories). I've added these absolute paths to code assistant, but whenever the external dependency changes version, the absolute paths become obsolete and I get a load of red flags. What I'd like to do is to be able to add a path like

$modelsim/oem/include

to the code assistance C/C++ include paths and have it undergo shell-like variable substitution.
